SILO.

To all whom/it may concern:

Be it known that I, ALBERT E. DE AR- MoND, a citizen of the United States, resiflv ing at Chicago, in the county of Cook and btate of Illinois, have mvented a certain new and usetul Improvement in Silos, of

'which the following is a specification.`

My invention relates to a silo and has tor its object to provide new and useful im-4 provements relating thereto.

It is illustrated in 'the accompanying drawings, wherein- Figure 1 is a cross section through a silo containing my invention; Fig. 2, a horizontal detail section; Fig. 3, a horizontal detail section through' a modification; Fig. 4, a de# tail cross section; Fig. 5, a detail of the con necting devices. A

Like parts are indicated by the same letters in all the figures.

A is t-he base or bottom above which rises a circular wall surmounted by a roof. This f'all is composed of aseries of uprightstuds B preferably U-shaped. From the web portion of each of these uprights is struck out w a tongue B1 .leaving the opening through B. to lock the parts together.

lproject-s as indicated in Fig. 4t.

which the tongue of the'next adjacent stud Each of these tongues in the form shown is provided with a-short upuuirdly struck strap l at each end, the straps ot' one registering` with those of another so as to leave an opei'iing l throuo'h which may be passed thc nail In the modified form shown in Fig". 3 the tongues are omitted and a cable C encirelesy the studi, heing attached thereto in any desired manner.

D, D are sheets ot'` lath material preterably in the form o'lE metallic lathing or some forni of woven wire material.

E, E is the coating or coveringl on thi-v intcrior and exterior ot the wall. 'lhs finishes the circular silo wall. F, if are openings therethrough admitting air from the exterior into the hollow fall.

The roof isot any desired construction and may be made otl material .similar to that used in the wall. This root is preferably composed of the upper and lower shells (t, G1 with the intermediate. air space alf. This air space connects with the air space in the circular vertical wall.

J is a tube at the top covered by the weather cap K and provided with the damper L. Into it opens the roof space G2.

The cable C may be used with either form Specification of Letters Patent.

of construction shown in Figs. 2 or il though it is not so necessary in the `ase ol the construction of Fig. 2, and the tongues and openings illustrated inV Figs 2 and 4 may be used in the structure of Fig. 3 though they are not there so necessary. The tongues are preferably bent to one side as indicated in Fig. 5 so as to make an angle in the horizontal plane with the web of the stud. This is to bring the tongue through the opening of the next stud. Ot course, mean's other than those shown could be used to secure the tongues together.

I have shown in my drawings a complete form of the structure capable of practical application, but I realize that various changes could be made without departing from the spirit of my invention. I therefore wish my drawings to be taken as in a sense diagrammatic and intended simply to illustrate one form of my invention and suggest others.

The upright studs could be of various structures and might consist. as indicated cach of a single channel bar or of two outer ends or bars of any desired shape connected by any desired cross pieces, braces or webs and there might be one or more such tongues on any given horizontal section and the same might be placed near either edge orat the middle ot' such stud and ,such tongue might .he struck as indicated or attached in any desired manner.

The use and operation of my invention are as follows: In the construction ot silos it ot' course, desirable to have the thinnest possible wall and to'lnwe it vertical on both sides. and to have it ventilated. All these things l accomplish in the best possihlennurner hy my invention. The studs are .set up and ysipiiorted in position in any desired manner and this is very simple i li' the tongues and openings are employed, for cach .stud is locked to thc next by the tongue and the pin. At the saine, time, or with any other meansL ot connecting the vertical studs together, they may he surrounded by a securing' cable. This is not usually necessary where the tongues are properly connected together. When the parts have heen thus assembled wc have a circular cage. To this inside and outside, is secured the latliing` material and on that. is placed the finished coating. This con'lplctes the vertical wall, the proper openings being made or lett as the work progresses. The Ventilating open ings at the outside bottom portion of the wall can be made as desired. The roof, as

above Suggested, is placed in position and its vopen space connected Withthe space in the Wall. The Ventilation space in the vertical Wall is preferably not Otherwise connected with the interior of the silo. There is, therefore, a continuously moving current of i air upwardly and outwardly through the ventilation spaces in the wall and roof with* out using the interior ofthe silo as any portion of the channel for such air. The air from the silo itself assists in furnishing a draft by passing out through the tube at the top. The damper L can Control this passage.
